SSM框架中配置文件的汇总

SSM框架中配置文件的汇总

Mybatis框架中的配置文件

依赖导入：mysql驱动 ， c3p0连接池 ，mybatis

1.数据库配置文件: jdbcConfig.properties

(主要是用于配置数据库的相关信息及驱动信息)

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test
jdbc.username=root
jdbc.password=root 

2.MyBatis的xml映射文件：mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <properties resource="jdbcConfig.properties">

    </properties>
    <!--使用typeAliases配置别名，它只能配置domain中类的别名 -->
    <typeAliases>
        <package name="com.itheima.domain"></package>
    </typeAliases>

    <!--配置环境-->
    <environments default="mysql">
        <!-- 配置mysql的环境-->
        <environment id="mysql">
            <!-- 配置事务 -->
            <transactionManager type="JDBC"></transactionManager>

            <!--配置连接池-->
            <dataSource type="POOLED">
                <property name="driver" value="${jdbc.driver}"></property>
                <property name="url" value="${jdbc.url}"></property>
                <property name="username" value="${jdbc.username}"></property>
                <property name="password" value="${jdbc.password}"></property>
            </dataSource>
        </environment>
    </environments>
    <!-- 配置映射文件的位置 -->
    <mappers>
        <package name="com.itheima.dao"></package>
    </mappers>
</configuration>

Spring框架中的配置文件

1. Spring中整合Mybatis的相关配置文件：spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!-- 配置账户的持久层-->
    <bean id="accountDao" class="com.itheima.dao.impl.AccountDaoImpl">
        <!--<property name="jdbcTemplate" ref="jdbcTemplate"></property>-->
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!--配置JdbcTemplate
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"></property>
    </bean>-->

    <!-- 配置数据源-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/eesy"></property>
        <property name="username" value="root"></property>
        <property name="password" value="1234"></property>
    </bean>
</beans>

2.Spring中整合service层的配置文件：spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
    <context:component-scan base-package="com.itheima"></context:component-scan>
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!-- 配置数据源-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/spring"></property>
        <property name="username" value="root"></property>
        <property name="password" value="root"></property>
    </bean>
    <!-- spring中基于XML的声明式事务控制配置步骤
        1、配置事务管理器
        2、配置事务的通知
                此时我们需要导入事务的约束 tx名称空间和约束，同时也需要aop的
                使用tx:advice标签配置事务通知
                    属性：
                        id：给事务通知起一个唯一标识
                        transaction-manager：给事务通知提供一个事务管理器引用
        3、配置AOP中的通用切入点表达式
        4、建立事务通知和切入点表达式的对应关系
        5、配置事务的属性
               是在事务的通知tx:advice标签的内部
     -->
    <!-- 配置事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
   <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

SpringMVC框架中的配置文件
